Title: Improvements in and relating to liquid reservoirs for aircraft
Inventor: CLARK GEORGE
IPC: B64D37/22
Filed: 1960-03-22
Abstract: 897,329. Liquid reservoirs for aircraft. ENGLISH ELECTRIC CO. Ltd. March 17, 1961 [March 22, 1960], No. 10182/60. Class 69 (1). In the liquid reservoir A for aircraft which is claimed, liquid returning at I from a consumer enters tangentially at D into an inner vortex ring E in a de-aeration chamber F and overflows the edges thereof to emerge through ports H into a plenum chamber B which is inside the reservoir A and has restricted passages J on top and bottom for bleeding air and liquid. Air freed from the liquid in the vortex is vented from the chamber F through a pipe V whilst de-aerated oil is fed to the consumer through a pipe O. The plenum chamber is filled with oil, but the oil level in the outer shell is at M, the flow of oil being as indicated by the arrows. Due to suction from the vortex a balance-pipe K returns the oil from the outer shell to the chamber B at a rate equal to the normal leakage through the passages J. If the reservoir is inverted air from the oil escapes through the pipe K into the shell and returns to the vortex through an annular pipe L for at least as long as the lever M is above the pipe L (Fig. 3, not shown).

Filed: 1949-04-19
Abstract: 688,205. Shoots; endless conveyers. BARKER, N. April 4, 1950. [April 19, 1949] No. 10318/49. Class 78 (i). A device for transferring material or articles from one conveyer to another conveyer or a shoot consists of a tilting or tiltable table, plate or the like which is pivoted, swivelled or hinged in such a way that it can be placed in a downwardly inclined position to permit the material or articles to pass straight through or forwardly, and can be tilted or inclined to cause such material or articles to be diverted laterally by it on to a transversely or angularly arranged conveyer or shoot. In one form the plate 4 is mounted on a diagonal hinge 13 supported in bearings 16, 18. The plate is formed with an upturned flange 6 at one side, Fig. 4, and is made concave at 10 towards its other side 5 and front edge 8. A delivery belt 1 is lapped over pulleys 2, 3, Fig. 5, and continues in a parallel direction. By tilting the plate about the hinge material passing along the belt 1 either passes forwardly over the plate to its continuation at the lower level, or is diverted to a cross-conveyer 11, A prop 26, Fig. 2, is provided to hold the plate in the forward delivery position, and this prop may be the piston of a piston cylinder actuator for tilting the plate. In the form shown in Fig. 5 the mounting for the plate 4 is a ball joint 33 and the plate can thus be tilted in any desired direction by proportionate amounts of lifting of the two forward corners. The plate 4 has in this case a flange 29 at each side and no curvature at the forward edge 8. Rods 40 secured to the corners have each a ball joint 43 for the piston rod 35 of a piston cylinder actuator, not shown.

Filed: 1930-04-02
Abstract: 348,320. Integrating - apparatus. ENGEL, F. V. A. E., 3, Creffield Road, Ealing Common, London. April 2, 1930, No. 10450. [Class 106 (iv).] In integrating-mechanism for fluid flow meters in which a movement of the measuring element is obtained in linear proportion to the rate of flow above a certain rate a variable ratio toothed gearing is provided to control the movement of the measuring element with respect to that part of the rate of flow which is non-linear. In the form shown in Figs. 1 and 5, a ratchet wheel 2, secured to the driving spindle 1 of a counting mechanism 3, is adapted to be actuated by one or other of the pawls 15 on a lever 12 secured to the hub of a wheel 13 forming part of a clock or other constant speed driving mechanism. The period of engagement of a pawl with the ratchet wheel is controlled by a pair of discs 7, 9 with partially flanged rims 8, 10 overlying the teeth of the ratchet wheel. The disc 7 is secured to a fixed sleeve 5 on the casing 6 whilst the disc 9 is secured to a spindle 11 operatively connected to the spindle 20 of the measuring device. In the zero rate of flow position the rims are disposed to prevent engagement of the pawls with the teeth of the ratchet wheel. At any other rate the disc 9 is displaced to uncover part of the wheel and the pawl actuates the wheel proportionally to the rate of flow. Disengagement of the pawl is effected by means of the leading edges of the rims 8, 10 which are rounded at a<1> to engage a shaped projection on the lower part of the pawl, the projection maintaining the tip of the pawl out of engagement with the rim after withdrawal. The operative connection between the spindles 11, 20, Fig. 2, is effected by gearing 17, 18, 19, 21 so arranged that at low rates of flow when the movement is non-linear the sector 19 drives the wheel 17 and when the movement is proportional to the rate of flow the mutilated wheel 21 drives the larger wheel 18, the greater movement at low rates being thus compensated.

Abstract: 1,006,857. Tunnel rectifier pulse circuits. NATIONAL CASH REGISTER CO. March 12, 1964 [March 26, 1963], No. 10502/64. Heading H3T. An amplitude-sensitive gate comprises a pair of tunnel rectifiers having pulses fed in pushpull to one terminal of each. Fig. 1 shows a circuit for amplifying the output of sense windings in a magnetic store of the type described in Specification 1,006,856. The tunnel rectifiers 20 are normally biased to the centre of their non-conductive region by a voltage of + 250 mV on lead VST, thus preventing transmission of spurious pulses on lines 11 . . . 13. When the store is read, the voltage on lead V ST  is reduced to +25 mV so that - 50 mV pulses on lines 11 . . . 13 (corresponding to a " 1 ") drive the appropriate tunnel rectifier 20 into its backward rectifying region and are transmitted to the amplifier 24, whilst lower amplitude pulses (corresponding to a " 0 ") are not transmitted. Negative pulses are fed to amplifier 24 when either positive or negative pulses of sufficient amplitude are received on lines 11 . . . 13 during the presence of the gating pulse on lead V ST . In Fig. 3 (not shown) a plurality of circuits each comprising a pair of tunnel rectifiers feed a common amplifier 24.
